Creative Warrior Tendinopathy | Flexor Digitorum superficialis/Flexor Digitorum Profundus Tendinopathy
Creative warrior tendinopathy is a condition that affects two muscles/tendons in your forearm, wrist, and fingers. Tendons are like little ropes that connect your muscles to your bones, and they help you move specific joints. When you play video games or use your wrist and fingers a lot, these tendons can get irritated and swollen, causing pain. These tendons in particular are what allows each person to bend their fingers and click/push buttons and can be seen in the highlighted color to the right.
This diagnosis is termed “Creative Warrior Tendinopathy” due to the frequent occurrence in Fortnite gamers. In Fortine, gamers are often switching between weapons or making/editing builds in a very rapid manner. This leads to extremely high APMs (Actions Per Minute) which can lead to overuse of the finger flexor muscles/tendons. Through improper positioning, poor conditioning, or inadequate rest these tendons will take the brunt of this and elicit pain. This name “Creative warrior tendinopathy is also interchangeable with Flexor digitorum superficialis/flexor digitorum profundus (FDS/FDP) tendinopathy, the two muscles involved in this injury. This diagnosis is vastly different from carpal tunnel syndrome as carpal tunnel from gaming is much less common than many know and believe. Discussed below are just a few simple, but effective ways to fix wrist pain from gaming.
Gamers are likely to begin experiencing pain and discomfort while playing and a sore, achey, or stiff feeling after in the area indicated above. Weakness is also likely to be present with gripping and moving the mouse. This is likely to decrease performance and alter the gameplay of the individual where movements may be slowed or less precise. Pain will be worse with any gripping or pinching required throughout the day such as shaking up a protein shake, pulling a laptop/books out of a backpack, or gripping a dumbbell.

Gamers use their fingers a lot! Gamers are at risk because of the long durations we play. Oftentimes this means we are taking less rest breaks when we are in the zone because we don’t always think to put our body first. Pain is something that can be reduced from distractions and gaming is a good distractor which makes it hard for gamers to know when to stop due to pain. Gamers are also at risk because of the specific motions required when playing. Computer gamers in particular are at an increased risk compared to mobile and console gamers due to the nature of the games and the speed/force they need to push/click buttons. Each time the mouse is clicked, these muscles/tendons are being used. It is less about the amount that they are clicked, but more about the force gamers are putting into each button click. The greater the speed and force, the greater the muscle stress and activation (Yoo, 2015).
Returning from this injury takes a concerted effort, but can be done without much time away from the game. Below are a few steps that individuals need to understand and take when pain in this area occurs.
Additional tip: Consider utilizing lifting hooks to help decrease the muscle recruitment necessary for pulling or certain gripping movements while lifting such as deadlifts, rows, bicep curls, lat pulldowns, etc. This should only be used when pain is present and not as something to rely on for all training.

*Surgery is very rarely required in order to effectively treat
The diagnosis was explained in short above, but for those wanting to know and learn more this is for you.
Specifically, this diagnosis is looking at two tendons (connect muscle to bone) which are responsible for bending (flexing) the fingers. These tendons can feel irritated at various points such as the wrist crease as they run from near the elbow into the tips of the fingers. Through repetitive use, inadequate amounts of rest, or forceful clicking the tendon can experience inflammation which if ignored may lead to structural damage over time. This overuse leads to a pain response to warn the body of damage so that individuals will stop the aggravating activity.
The muscle originates at the medial epicondyle and shaft of the radius where it attaches to the volar aspect of the middle phalanx of digits 2-5.
Both muscles also help with bending the wrist towards the palm (wrist flexion)
It should also be known that gaming is not the only activity to bring on this condition and certainly other lifestyle factors play a role. School, work, and other hobbies can also further stress this tendon and can be important to thoroughly evaluate as well. This injury specifically can also be common in climbers.
Ganglion Cyst-A fluid filled sac that grows from the lining of our joints, often times needs to be removed. This is important to seek medical advice from a doctor regarding treatment.
Wrist Instability- The wrist is comprised of several different supporting structures such as ligaments (Hold bone to bone) and tendons (Hold muscle to bone). Certain individuals may have anatomical variations in the length or alignment of their bones or even experience an injury throughout their life. This can lead to increased strain and demand on the supporting structures which may result in pain and overall decreased performance.
There are several approaches to take in order to prevent this injury from occurring or coming back. There are 3 main factors to first focus on and address, but it is also important to keep in mind other secondary factors which can be helpful to address.
